Answer:
15 feet
Step-by-step explanation:
It is given that Quadrilateral ABCD is similar to Quadrilateral EFGH. This means that the corresponding sides of these two quadrilateral will be in the same proportion.
i.e.
Ratio of two corresponding sides would be the same. We are given longest three sides of ABCD and shortest two sides of EFGH. Let the 4th sides of ABCD i.e. the shortest side be x.
So, the ratio of the shortest sides of two quadrilaterals would be the same as the ratio of second shortest sides.
So,

So, the 4th side on quadrilateral ABCD would be 15 feet. None of the options match with the answer.
Answer:
C. 9
Step-by-step explanation:
81 = 9 x 9
18 = 9 x 2
so the greatest common factor (GCF) of 81 and 18 : 9
Answer is C. 9
You have to keep order of operations in mind.
1. Take care of the parentheses; distribute.
-3+6x-3=-20-8x
Simplified: 6x-6=-20-8x
2. Isolate the x variable.
Add 8x to both sides and add 6 to both sides.
14x=-14
3. Solve for x.
Divide by 14 on both sides.
x=-1
Answer:
69
Step-by-step explanation:
What is the graph?
-18 + x = -11
Let's add 18 to both sides
x = 7
